BUC
The IF input is a 50 ohm type-N connector. The input is to be applied here (950-1700 MHz for Extended
Band; 950-1450 MHz for Standard Band). Also, the 10 MHz signal input is diplexed onto this line.
Therefore, the IF signal and 10 MHz reference are both traveling on this line. The connector is DC -
blocked. Do not /- 50VDC on this port.
The 10-MHz signal should be accurate /- 1ppm, otherwise the BUC may have difficulty phase
locking to it. The 10-MHz should be free of sideband spurs, particularly close-in (under 100 kHz), as these
may also cause failure to lock. Power level of the 10 MHz reference signal should be +/-5 dBm.
SSPA
In the SSPA-only configuration, this is the RF input. It is a precision type-N connector, with performance
to 18GHz. No 10 MHz reference is required for SSPA-only operation.
